Note
Weekend
Report of work
- Pump down for central area was postponed for 2 weeks.
- Type B: BS still has some trouble, it was decided to open chamber again.
- Type Bp: OSEMs were fixed, and it looks OK. Beam position on QPD was off. PRM needs more tuning and measurement. It will be done in the next week.
- Y end temperature became low by 3 degree.
- IOO: Found touching AOM driver and fork, and it was making a big group loop. Once it was released the noise became much smaller.
Work plan
- Yend pump down start today.
